Hovercraft Bassline

I wanna know how to make that sort of bassline that Zen used in Hovercraft. That track was massive and im trying to experiment with a few basslines that sound a bit like that. Dont worry... I'm not copying his track... there is just a section in one of mine that I thought would sound pretty mad if it had that same sort of vibe in it.

Im trying some oscilatored mid range bass (layered over some sub bass) with a bit of a low pass filter on it. It almost sounds right, but there's something not right.

I got decently close by layering an accordion (before I knew hoverboard was from B2TF, nevermind, thought it had something to do with french influences) with a saw wave and mixing around with processing, voicing and levels a wee bit.
